| Abstract: | Summary The new mixed-ligand complexes of d-electron metals (M(II)=Mn, Ni, Cu) with 2,2'-bipyridine (2-bpy) and mono- or dichloroacetates were prepared as crystalline solids. The general
formulae of the synthetized complexes are: Cu(2-bpy)2(CClH2COO)2·2H2O, Mn(2-bpy)2(CCl2HCOO)2, M(2-bpy)2(CCl2HCOO)2·2H2O (M(II)=Ni, Cu). The compounds were characterized by chemical analysis, IR and VIS spectroscopy. Their magnetic, molar conductivity
and thermal properties also were studied. During heating in air complexes decompose via different intermediate products to
metal oxides. A coupled TG-MS system was used to analyse the principal volatile thermal decomposition (or fragmentation) products
of 2,2'-bipyridine-chloroacetato complexes. |
